Description

Technical Field

[0001] The present application relates to the technical field of power plugging, and in particular to a plugging component, a plugging device, a seat and a vehicle. Background Art

[0002] Car seat audio headrests are becoming increasingly popular. Many models, especially new energy vehicles, now feature the driver's audio headrest, allowing for private calls, navigation, and exclusive music listening. Because power must be supplied to the audio system and sound quality must be maintained, most seats utilize a solution that routes the audio wiring harness from the headrest rod and connects it to the vehicle through the seat's internal wiring harness for power. To prevent users from ripping the wiring harness when removing the headrest, most headrests are designed to be non-detachable or feature a concealed lock to prevent removal.

[0003] Compared to traditional models, new energy vehicles focus not only on the driving experience but also on creating versatile interior spaces, home settings, and camping experiences. The non-detachable headrests restrict the ability to fold or recline the seats, significantly limiting the creation of these spaces. Utility Model Content

[0004] The present application provides a connector component, a connector device, a seat and a vehicle, aiming to realize the pluggable function and stable power supply of an audio headrest.

[0005] In a first aspect, the present application provides a connector component, comprising:

[0006] A support member, wherein the support member has a sliding channel therein, the sliding channel has a first opening, and an inner wall of the sliding channel is provided with a limiting protrusion;

[0007] a first connector assembly installed in the sliding channel and capable of moving along the sliding channel;

[0008] a limiting assembly, the limiting assembly being located in the sliding channel and being capable of sliding along the sliding channel relative to the support member;

[0009] The limiting assembly can abut against the limiting protrusion along a first direction, so that the first connector assembly is fixed at a first position in the sliding channel.

[0010] In this application, the area between the limiting protrusion and the first opening is defined as the limiting area. When the limiting protrusion, through the limiting assembly, limits the first connector assembly to any position in the limiting area, the first connector assembly can be completely located within the sliding channel. In this case, the first connector assembly is positioned close to the first opening, which facilitates mating with the second connector assembly while reducing the risk of damage caused by partial exposure of the first connector assembly.

[0011] Alternatively, when the limiting protrusion limits the first connector assembly to any position in the limiting area through the limiting assembly, part of the first connector assembly can be exposed outside the sliding channel through the first opening to facilitate cooperation with the second connector assembly.

[0012] In one possible design, along the first direction, the support member has a top and a bottom, the top is provided with a first blocking portion, the bottom is provided with a second opening and a second blocking portion, the second opening is arranged opposite to the first opening, and the second blocking portion is arranged opposite to the first blocking portion.

[0013] In the present application, by providing the first blocking portion and the second blocking portion, a bidirectional anti-detachment effect can be achieved for the first connector assembly, thereby ensuring the stability of the operation of the connector device.

[0014] In one possible design, the limiting assembly includes an elastic member and at least two limiting members. Along the second direction, the two ends of the elastic member are respectively connected to the two limiting members, and the limiting members are in a compressed state so that the limiting members abut against the inner wall of the sliding channel.

[0015] In the present application, the two limiting members abut against the inner wall of the sliding channel and compress the elastic member, so that the elastic member is in a compressed state and provides thrust to the two limiting members to maintain the limiting members abutting against the inner wall of the sliding channel and keep them at any position.

[0016] In a possible design, the limiting assembly further includes a housing, the elastic member and the two limiting members are mounted on the housing, and at least portions of the two limiting members can extend out of the housing;

[0017] One of the outer side wall of the shell and the inner side wall of the sliding channel is provided with a sliding block, and the other is provided with a sliding groove, and the sliding block is slidably matched with the sliding groove.

[0018] In the present application, a slider is provided to slide with the slide groove to limit the movement trajectory of the limit assembly, thereby ensuring the stability of the movement of the first connector assembly in the sliding channel.

[0019] In a second aspect, the present application provides a connector, which includes the connector member described above and a second connector assembly, wherein the second connector assembly is plugged into and mated with the first connector assembly and is electrically connected to the first connector assembly.

[0020] In this application, the first connector assembly is electrically connected to the vehicle power supply through the backrest wiring harness, and the second connector assembly is electrically connected to the audio system in the headrest through the audio wiring harness. When the first connector assembly is electrically connected to the second connector assembly, the audio wiring harness and the backrest wiring harness can be electrically connected, and the audio system electrically connected to the audio wiring harness is powered by the vehicle power supply electrically connected to the backrest wiring harness.

[0021] The first connector assembly and the second connector assembly can be detachably connected. Specifically, at least a portion of the second connector assembly can extend through the first opening into the sliding channel to mate with the first connector assembly, thereby achieving electrical and mechanical connection between the second connector assembly and the first connector assembly. When the headrest is removed from the backrest, the audio wiring harness and the backrest wiring harness can be disconnected by removing the first connector assembly and the second connector assembly, preventing the wiring harness from being torn when the headrest is removed. After the headrest is removed, the seat can be folded in half and tilted backward, meeting the user's various usage scenarios and improving the user experience.

[0022] Furthermore, when the first connector assembly is mounted in the sliding channel, it can slide relative to the support member along the sliding channel. Specifically, the first connector assembly and the second connector assembly can slide within the sliding channel when in a mating state. When the angle of the headrest needs to be adjusted, that is, when the headrest rotates relative to the backrest, the second connector assembly mounted on the headrest rotates with the headrest, driving the first connector assembly connected thereto to slide within the sliding channel. Specifically, when the headrest rotates, the first and second connector assemblies can move synchronously, remaining connected, to ensure that normal power is maintained during adjustment of the headrest angle.

[0023] In one possible design, the first connector assembly includes a first connector and a first conductive member, the first conductive member is mounted on an outer side wall of the first connector, and the first connector assembly is provided with a limiting portion;

[0024] The second connector assembly includes a second connector and a second conductive member, the second connector is provided with a receiving cavity, the second conductive member is installed in the receiving cavity, a limited portion is provided in the receiving cavity, and the second connector assembly is movable relative to the support member so that the connector device has at least a first state or a second state;

[0025] In the first state, a portion of the structure of the second connector assembly can extend into the sliding channel, so that at least a portion of the first connector assembly can extend into the accommodating cavity, the first conductive member and the second conductive member are electrically connected, and the limiting portion cooperates with the limited portion; in the second state, the first conductive member and the second conductive member are electrically disconnected, and the limiting portion and the limited portion are released from cooperation.

[0026] In the present application, when the second connector assembly extends into the sliding channel through the first opening, at least part of the structure of the first connector assembly can extend into the accommodating cavity, so that the limiting portion cooperates with the limited portion, and the first conductive member is electrically connected to the second conductive member, thereby realizing the simultaneous electrical connection of the first connector assembly and the second connector assembly.

[0027] When the first connector assembly is out of the accommodating cavity, the limiting portion and the limited portion are released from engagement, and the first conductive member and the second conductive member are electrically disconnected. At this time, the second connector assembly is out of the sliding channel, so that the first connector assembly and the second connector assembly are completely separated.

[0028] In this application, the limiting portion cooperates with the limited portion to ensure the stability of the electrical connection between the first conductive member and the second conductive member when the first connector assembly and the second connector assembly in the mating state move in the sliding channel.

[0029] In a possible design, along the first direction, the resistance to separation of the first connector assembly and the second connector assembly is a first force value F1;

[0030] Along the first direction, after the first connector assembly and the second connector assembly are mated, when the two move below the limiting protrusion, the resistance exerted by the limiting protrusion is a second force value F2;

[0031] F1 and F2 satisfy: F2>F1.

[0032] In the present application, this embodiment sets F2>F1 so that the external force applied to the first connector component and the second connector component to achieve the matching between the two will not cause the limit component to move downward to below the limit protrusion, so that the first connector component can complete the matching with the second connector component 13 within the limiting area, thereby facilitating the matching between the first connector component and the second connector component.

[0033] In a possible design, along the first direction, the resistance to separation of the first connector assembly and the second connector assembly is a first force value F1;

[0034] During the sliding of the limiting assembly along the sliding channel, the resistance of the inner wall of the sliding channel to the limiting assembly is a third force value F3; F1 and F3 satisfy: F1>F3.

[0035] In the present application, by setting F1>F3, it is achieved that when the first connector component and the second connector component are in a mating state, when the second connector component is pressed, the second connector component can drive the first connector component and the limit component to move synchronously in the sliding channel to adjust the position of the headrest, and prevent the first connector component from being separated from the second connector component, thereby improving the reliability of the electrical connection between the first conductive member and the second conductive member when adjusting the position of the headrest.

[0036] In a possible design, along the first direction, the resistance to separation of the first connector assembly and the second connector assembly is a first force value F1;

[0037] Along the first direction, after the first connector assembly and the second connector assembly are mated, when the two move to above the limiting protrusion, the resistance exerted by the limiting protrusion is a fourth force value F4;

[0038] F1 and F4 satisfy: F1>F4.

[0039] In this application, by setting F1>F4, when the user applies an external force of the fourth force value F4 to make the first connector component and the second connector component move upward over the limiting protrusion in the mated state, the fourth force value F4 will not cause the first connector component and the second connector component to be disconnected.

[0040] In a third aspect, the present application provides a connector, comprising:

[0041] A support member, wherein the support member has a sliding channel therein;

[0042] a first connector assembly, the first connector assembly being installed in the sliding channel and being movable along a first direction, the first connector assembly comprising a first connector and a first conductive member, the first conductive member being installed on an outer side wall of the first connector, and the first connector assembly being provided with a limiting portion;

[0043] a second connector assembly, the second connector assembly comprising a second connector and a second conductive member, the second connector assembly being provided with a receiving cavity, the second conductive member being mounted within the receiving cavity, the receiving cavity being provided with a limited portion, the second connector assembly being movable relative to the support member so that the connector device has at least a first state or a second state;

[0044] In the first state, a portion of the structure of the second connector assembly can extend into the sliding channel, so that at least a portion of the first connector assembly can extend into the accommodating cavity, the first conductive member and the second conductive member are electrically connected, and the limiting portion cooperates with the limited portion; in the second state, the first conductive member and the second conductive member are electrically disconnected, and the limiting portion and the limited portion are released from cooperation.

[0045] In the present application, when the second connector assembly extends into the sliding channel through the first opening, at least part of the structure of the first connector assembly can extend into the accommodating cavity, so that the limiting portion cooperates with the limited portion, and the first conductive member is electrically connected to the second conductive member, thereby realizing the simultaneous electrical connection of the first connector assembly and the second connector assembly.

[0046] When the first connector assembly is out of the accommodating cavity, the limiting portion and the limited portion are released from engagement, and the first conductive member and the second conductive member are electrically disconnected. At this time, the second connector assembly is out of the sliding channel, so that the first connector assembly and the second connector assembly are completely separated.

[0047] In this application, the limiting portion cooperates with the limited portion to ensure the stability of the electrical connection between the first conductive member and the second conductive member when the first connector assembly and the second connector assembly in the mating state move in the sliding channel.

[0048] In a possible design, along the first direction, the outer side wall of the first connector assembly is provided with at least two spaced-apart protrusions, at least two of the protrusions form the limiting portion, and the limited portion is a structure protruding toward the center of the accommodating cavity.

[0049] In the present application, the limiting portion is formed by at least two protrusions surrounded along a first direction, and the limited portion is a structure that protrudes toward the center of the accommodating cavity. When the limiting portion and the limited portion cooperate, the limited portion is clamped between the two protrusions, and the limited portion is limited from being separated from the limiting portion by the abutment of the relative end faces of the limited portion and the protrusion, thereby reducing the risk of the first connector assembly and the second connector assembly falling off.

[0050] Among them, at least one of the protruding portion and the limited portion is elastic, so that during the process of mating or releasing the first connector component and the second connector component, at least one of the protruding portion and the limited portion can be squeezed to enable the limited portion to be mated or released with the limiting portion.

[0051] In a possible design, the protrusion is provided on the first conductive member, and the second conductive member is provided on at least one side of the limited portion along the first direction.

[0052] In this application, the first conductive member can be a conductive spring, the insulating member can be a plastic member, and the raised portion is formed by bending a portion of the first conductive member. When the first connector assembly is mated with the second connector assembly, the raised portion abuts against a portion of the second conductive member corresponding along the second direction, thereby achieving electrical connection between the first and second conductive members.

[0053] The present application provides a protruding portion on the first conductive member and provides a second conductive member on both sides of the limited portion along the first direction, so that the protruding portion can abut against the second conductive member, thereby achieving contact and electrical connection between the first conductive member and the second conductive member, and can also limit the first connector assembly and the second connector assembly, thereby achieving a snap-fit ​​fit between the first connector assembly and the second connector assembly.

[0054] In one possible design, the second connector assembly further includes an insulating member;

[0055] The inner side wall of the accommodating cavity is provided with a slot, and the insulating member is installed in the slot;

[0056] The second conductive member is mounted on the insulating member.

[0057] In the present application, in order to ensure the structural strength of the second connector, the second connector is made of metal. Therefore, by providing an insulating member, the second connector is isolated from the insulating member to achieve insulation and protection effects.

[0058] The insulating member is provided with a snap-fitting groove, and the second conductive member is fixed to the insulating member by snapping into the snap-fitting groove. Alternatively, the second conductive member can be fixed to the insulating member by bonding. Alternatively, other methods can be used to achieve the fixing of the second conductive member to the insulating member, which are not limited in this application.

[0059] In a possible design, the limited portion is provided on the insulating component, and along the first direction, the second conductive component is provided on at least one side of the limited portion.

[0060] In this application, the first conductive member can be a conductive spring, the insulating member can be a plastic member, the raised portion is formed by bending a portion of the first conductive member, and the restricted portion is formed by a portion of the insulating member. When the first connector assembly is mated with the second connector assembly, the raised portion abuts against a portion of the second conductive member corresponding to the first connector assembly along the second direction, thereby achieving electrical connection between the first and second conductive members.

[0061] The present application provides a protruding portion on the first conductive member, a limited portion on the insulating member, and second conductive members on both sides of the limited portion along the first direction, so that the protruding portion can abut against the second conductive member, thereby achieving contact and electrical connection between the first conductive member and the second conductive member, and can also limit the first connector assembly and the second connector assembly, thereby achieving a snap-fit ​​fit between the first connector assembly and the second connector assembly.

[0062] In a possible design, the protrusion is provided on the first conductive member, and the limited portion is provided on the second conductive member.

[0063] In this application, the first and second conductive members may be formed as conductive springs. The raised portion is formed by bending a portion of the first conductive member, and the restricted portion is formed by bending a portion of the second conductive member. When the first and second connector assemblies mate, at least one of the restricted portion and the raised portion abuts against a corresponding portion of the conductive structure along the second direction, thereby achieving electrical connection between the first and second conductive members.

[0064] For example, in one scenario, the restricted portion maintains contact with the corresponding first conductive member along the second direction, while the raised portion does not maintain contact with the corresponding second conductive member along the second direction. In this case, the electrical connection between the restricted portion and the first conductive member enables electrical connection between the first conductive member and the second conductive member. It should be noted that even if the raised portion does not maintain contact with the second conductive member, if the spacing between the raised portion and the second conductive member along the second direction X is less than the thickness of the restricted portion along the second direction, the raised portion still serves to limit the restricted portion.

[0065] In another embodiment, the raised portion maintains contact with the corresponding second electrical component along the second direction, while the restricted portion does not maintain contact with the corresponding first electrical component along the second direction. In this case, the electrical connection between the raised portion and the second electrical component enables electrical connection between the first and second electrical components. It should be noted that even if the restricted portion does not maintain contact with the first electrical component, the spacing between the restricted portion and the first electrical component along the second direction is less than the thickness of the raised portion along the second direction, and the raised portion still serves to limit the restricted portion.

[0066] In another embodiment, the protrusion is kept in contact with the second electrical component corresponding to the second direction, and the limited portion is kept in contact with the first conductive component corresponding to the second direction. At this time, the protrusion is electrically connected to the second electrical component, and the limited portion is electrically connected to the first conductive component, thereby realizing electrical connection between one conductive component and the second conductive component.

[0067] The present application provides a protrusion on the first conductive member and a limited portion on the second conductive member, thereby achieving contact and electrical connection between the first conductive member and the second conductive member, while also limiting the first connector assembly and the second connector assembly, thereby achieving a snap-fit ​​fit between the first connector assembly and the second connector assembly.

[0068] In a possible design, the protrusion is provided on the first connector, and along the first direction, the first conductive member is provided between two of the protrusions;

[0069] The limited portion is provided on the second conductive member.

[0070] In this application, the second conductive member may be a conductive spring. The protrusion is formed by a portion of the first conductive member protruding outward, and the restricted portion is formed by a portion of the second conductive member being bent. When the first connector assembly is mated with the second connector assembly, the restricted portion abuts against the portion of the first conductive member corresponding to the first connector assembly along the second direction, thereby achieving electrical connection between the first and second conductive members.

[0071] The present application provides a protrusion on the first connector, and a first conductive member between the protrusions, and a limited portion on the second conductive member, so that the limited portion abuts against the first conductive member, thereby achieving contact and electrical connection between the first conductive member and the second conductive member, and also limiting the first connector assembly and the second connector assembly, thereby achieving a snap-fit ​​fit between the first connector assembly and the second connector assembly.

[0072] In a fourth aspect, the present application provides a seat, comprising:

[0073] Backrest;

[0074] a headrest, the headrest being detachably mounted above the backrest and capable of adjusting its position relative to the backrest;

[0075] A plug-in device, wherein the plug-in device is the plug-in device described above;

[0076] The support member is installed on the backrest, and the second connector assembly is installed on the headrest.

[0077] In this application, by designing the above-mentioned connector, the headrest and the backrest are detachably connected, and normal power is ensured when the headrest is reinstalled on the backrest and the position is adjusted up and down.

[0078] In one possible design, along the first direction, after the first connector assembly and the second connector assembly are mated, when the two move below the limiting protrusion, the resistance exerted by the limiting protrusion is a second force value F2;

[0079] Along the first direction, the resistance of the support member to separate from the backrest is a fifth force value F5;

[0080] F2 and F5 satisfy: F5>F2.

[0081] In this application, when the user applies external force to the docking device to cause the limit assembly to move upward over the limit protrusion, the external force is less than the fifth force value F5 of the support member to separate from the backrest, preventing the docking device from separating from the backrest when being pulled out.

[0082] In a fifth aspect, the present application provides a vehicle, comprising:

[0083] body;

[0084] A seat is the seat described above, and the seat is installed on the vehicle body.

[0085] In this application, by setting up the configuration of detachable headrests, the seats can be folded in half or tilted back, which greatly improves the experience of creating a variety of spaces, home scenes and camping experiences in the car. BRIEF DESCRIPTION OF THE DRAWINGS

[0117] With the advent of the electrification era, vehicle electrical configurations are becoming increasingly sophisticated, and audio headrests are becoming increasingly common. These headrests are connected to the vehicle's power supply via wiring harnesses, enabling functions such as calling, navigation, and music playback. However, in related technologies, the wiring harness connecting the audio headrest to the vehicle's power supply lacks a detachable function, rendering the audio headrest non-detachable or prone to wiring harness breakage during removal.

[0118] To this end, this embodiment provides a plug-in device to solve the above technical problems. The following describes in detail possible structures of the plug-in device with reference to the accompanying drawings.

[0119] like Figure 1 The figure shows a schematic diagram of a portion of the connector 1 structure, which includes a support member 11, a first connector assembly 12, a second connector assembly 13, an audio wiring harness 2, and a backrest wiring harness 3. In the connector 1 provided in the embodiment of the present application, when the first connector assembly 12 and the second connector assembly 13 are electrically connected, the audio wiring harness 2 and the backrest wiring harness 3 can be electrically connected. Since the vehicle power supply is connected to the backrest wiring harness 3, the vehicle power supply can thus be used to power the audio system (the audio system installed in the headrest).

[0120] The support member 11 and first connector assembly 12 are mounted on the backrest, while the second connector assembly 13 is mounted on the headrest. Specifically, the support member 11 is a metal frame structure, a plastic bracket structure, or the like. The support member 11 is mounted on the backrest (not shown) and has a first opening 112a through which the audio harness 2 extends to connect to the audio system.

[0121] Among them, 112a can be opened in the first blocking part 112 along the first direction Y. The first blocking part 112 is the top structure of the support member 11. The first blocking part 112 is used to prevent the first connector component 12 from falling out of the sliding channel 111, and at the same time can resist the second connector component 13 from bringing the first connector component 13 out of the sliding channel 111, thereby realizing the disengagement of the first connector component 12 and the second connector component 13.

[0122] The support member 11 further has a sliding channel 111 , and the first connector assembly 12 is installed in the sliding channel 111 so that the first connector assembly 12 can slide along the sliding channel 111 .

[0123] The support member 11 also has a second opening 113a. The first connector assembly 12 is electrically connected to the backrest wiring harness 3. The backrest wiring harness 3 is used to extend through the second opening 113a to be electrically connected to the vehicle power supply (not shown in the figure).

[0124] Among them, 113a can be opened in the second blocking portion 113 along the first direction Y. The second blocking portion 113 is the bottom structure of the support member 11, and the second blocking portion 113 is used to prevent the first connector assembly 12 from escaping from the sliding channel 111.

[0125] The second connector assembly 13 is electrically connected to the audio harness 2 in the headrest, which in turn is electrically connected to the headrest (and the audio system installed in the headrest). Therefore, when the first connector assembly 12 is electrically connected to the second connector assembly 13, the audio harness 2 is electrically connected to the seatback harness 3, and power is supplied to the audio system connected to the audio harness 2 via the vehicle power supply electrically connected to the seatback harness 3.

[0126] The first connector assembly 12 and the second connector assembly 13 can be detachably connected. Specifically, at least a portion of the second connector assembly 13 can extend into the sliding channel 111 through the first opening 112a to cooperate with the first connector assembly 12, thereby achieving electrical and mechanical connection between the second connector assembly 13 and the first connector assembly 12. Moreover, when the headrest is removed from the backrest, the audio wiring harness 2 and the backrest wiring harness 3 can be disconnected by removing the first connector assembly 12 and the second connector assembly 13, thereby preventing the wiring harness from being torn when the headrest is removed. After the headrest is removed, the seat can be folded in half and tilted backward, meeting the user's various usage scenarios and improving the user experience.

[0127] Furthermore, when installed in the sliding channel 111, the first connector assembly 12 can slide along the sliding channel 111 relative to the support member 11. Specifically, the first connector assembly 12 and the second connector assembly 13 can slide within the sliding channel 111 when in a mating state. When the headrest angle needs to be adjusted, that is, when the headrest rotates relative to the backrest, the second connector assembly 13 installed in the headrest moves with the rotation of the headrest, driving the connected first connector assembly 12 to slide within the sliding channel 111. Specifically, when the headrest rotates, the first and second connector assemblies 12, 13 can move synchronously while remaining connected, ensuring that power remains constant during headrest angle adjustment.

[0128] The specific structure of the detachable connection between the first connector assembly 12 and the second connector assembly 13 will be described below.

[0129] It should be noted that, hereinafter, the first direction refers to the direction in which the sliding channel 111 extends, and the second direction refers to a direction substantially perpendicular to the direction in which the sliding channel 111 extends.

[0130] like Figure 2 The figure shows a schematic diagram of the first connector assembly 12, which includes a first connector 121 and a first conductive member 122. The first conductive member 122 is mounted on the outer wall of the first connector 121. When the first connector assembly 12 is mated with the second connector assembly 13, the first conductive member 122 is used to conduct electricity with the second connector assembly 13. The second conductive member 122 is also used to electrically connect to the seatback wiring harness 3.

[0131] Along the first direction Y, the outer wall of the first connector assembly 12 is provided with at least two spaced-apart protrusions 122a, which enclose a stopper 122d. When the first connector assembly 12 is mated with the second connector assembly 13, the stopper 122d is used to limit the position of the second connector assembly 13.

[0132] like Figure 3 The figure shows a schematic diagram of the second connector assembly 13, which includes a second connector 131, a second conductive member 132, and an insulating member 133 (the insulating member 133 is described in detail below). The second connector 131 is provided with a receiving cavity 131a, and the second conductive member 132 is installed in the receiving cavity 131a. When the first connector assembly 12 and the second connector assembly 13 are mated, the second conductive member 132 can conduct electricity with the first connector assembly 12. The second conductive member 132 is also used to electrically connect to the audio wiring harness 2.

[0133] A limited portion 132a is provided in the accommodating cavity 131a and is a structure protruding toward the center of the accommodating cavity 131a along the second direction X. When the first connector assembly 12 is mated with the second connector assembly 13, the limited portion 132a is used to cooperate with the first connector assembly 12 for limiting position.

[0134] The connector 1 has at least a first state (mated state) and a second state (unmated state). Figure 4 The diagram shows the first connector assembly 12 and the second connector assembly 13 in a mating state. Figure 1 and Figure 4 In the first state, a portion of the second connector assembly 13 can extend into the sliding channel 111, allowing at least a portion of the first connector assembly 12 to extend into the accommodating cavity 131a. At this point, the first conductive member 122 and the second conductive member 132 are electrically connected, and the limiting portion 122d engages with the limited portion 132a.

[0135] like Figure 5 The diagram shows the first connector assembly 12 and the second connector assembly 13 in a disengaged state. In the second state, the first connector assembly 12 can be removed from the accommodating cavity 131a. At this time, the first conductive member 122 and the second conductive member 132 are electrically disconnected, and the limiting portion 122d and the limited portion 132a are disengaged. The second connector assembly 13 can further be removed from the sliding channel 111.

[0136] In this embodiment, when the second connector assembly 13 extends into the sliding channel 111 through the first opening 112a, at least a portion of the first connector assembly 12 can extend into the accommodating cavity 131a, causing the limiting portion 122d to engage with the limited portion 132a, electrically connecting the first conductive member 122 and the second conductive member 132. This achieves simultaneous electrical connection between the first connector assembly 12 and the second connector assembly 13, thereby electrically connecting the audio wiring harness 2 and the backrest wiring harness 3, and further electrically connecting the headrest to the vehicle power supply. When the angle of the headrest is adjusted, the cooperation of the limiting portion 122d and the limited portion 132a ensures the stability of the electrical connection between the first conductive member 122 and the second conductive member 132 as the first and second connector assemblies 12 and 13 in the engaged state move within the sliding channel 111, thereby maintaining a reliable electrical connection between the headrest and the vehicle power supply even when the headrest angle is adjusted.

[0137] When the first connector assembly 12 is removed from the accommodating cavity 131a, the limiting portion 122d is released from the limited portion 132a, and the first conductive member 122 and the second conductive member 132 are electrically disconnected. At this time, the second connector assembly 13 is removed from the sliding channel 111, so that the second connector assembly connected to the headrest and the first connector assembly connected to the backrest are disconnected, and the headrest can be removed.

[0138] Specifically, the limiting portion 122d is formed by at least two protrusions 122a surrounded by each other along the first direction Y, and the limited portion 132a is a structure that protrudes toward the center of the accommodating cavity 131a. When the limiting portion 122d cooperates with the limited portion 132a, the limited portion 132a is clamped between the two protrusions 122a, and the limited portion 132a is separated from the limiting portion 122d by the abutment of the relative end faces of the limited portion 132a and the protrusion 122a, thereby reducing the risk of abnormal detachment of the first connector assembly 12 and the second connector assembly 13.

[0139] Among them, at least one of the protrusion 122a and the limited portion 132a is elastic, so that during the process of mating or unmating the first connector component 12 and the second connector component 13, at least one of the protrusion 122a and the limited portion 132a can be squeezed to enable the limited portion 132a to be mated or unmated with the limiting portion 122d.

[0140] More specifically, in order to facilitate the engagement or disengagement of the restricted portion 132a with the restricting portion 122d, both the protruding portion 122a and the restricted portion 132a may be provided with a guide surface.

[0141] like Figure 6 The diagram shows the abutment between the raised portion 122a and the restricted portion 132a. Along the first direction Y, first guide surfaces 132a1 are provided on both sides of the restricted portion 132a, and second guide surfaces 122a1 are provided on both sides of the raised portion 122a. During the mating or dismating process between the restricted portion 132a and the restricting portion 122d, the abutment between the first guide surfaces 132a1 and the second guide surfaces 122a1 guides the relative movement between the raised portion 122a and the restricted portion 132a, thereby saving effort when inserting and removing the connector 1.

[0142] like Figure 7 FIG. 1 shows a schematic diagram of a second connector 131 in a specific embodiment. The second connector 131 has a receiving cavity 131a. A sidewall of the receiving cavity 131a is provided with a slot 131a1 for receiving an insulating member 133. Along the first direction Y, the lower sidewall of the slot 131a1 is provided with an opening 131a2 for facilitating the insertion of the insulating member 133.

[0143] like Figure 8 The second connector 131 and the insulating member 133 are shown in the structural diagram of the second connector assembly 13. The second connector assembly 13 includes the second connector 131 and the insulating member 133. The insulating member 133 is clamped in the clamping groove 131a1 through the opening 131a2. Figure 3 、 Figure 7 and Figure 8The second conductive member 132 is mounted on the insulating member 133. In this embodiment, to ensure the structural strength of the second connector 131, the second connector 131 is made of metal. Therefore, the insulating member 133 separates the second connector 131 from the second conductive member, providing insulation and protection, thereby preventing the second conductive member 132 from being electrically connected to the support member 11 through the second connector 131 and causing a short circuit.

[0144] The insulating member 133 may be provided with a snap-fit ​​groove (not shown), into which the second conductive member 132 is snapped. Alternatively, the second conductive member 132 may be fixed to the insulating member 133 by bonding. Alternatively, other methods may be used to secure the second conductive member 132 to the insulating member 133, which are not limited in this embodiment.

[0145] Similarly, a snap-fit ​​groove (not shown) may be provided on the outer side of the first connector 121, into which the first conductive member 122 is snapped. Alternatively, the first conductive member 122 may be fixed to the first connector 121 by adhesive bonding, or other methods may be used to secure the first conductive member 122 to the first connector 121, which are not limited in this embodiment.

[0146] The above is a possible structure for realizing the mechanical connection between the first connector assembly and the second connector assembly. The following describes in detail the specific manner in which the first conductive member and the second conductive member are electrically connected.

[0147] In one embodiment, the electrical connection between the first conductive member 122 and the second conductive member 132 may be achieved by direct contact between a portion of the first conductive member 122 and a portion of the second conductive member 132 .

[0148] For example, in some embodiments, please continue to refer to Figures 2 to 4 The raised portion 122a is provided on the first conductive member 122, and the restricted portion 132a is provided on the second conductive member 132. In this embodiment, the first conductive member 122 and the second conductive member 132 may be formed by conductive springs. The raised portion 122a is formed by bending a portion of the first conductive member 122, and the restricted portion 132a is formed by bending a portion of the second conductive member 132. When the first connector assembly 12 and the second connector assembly 13 are mated, at least one of the restricted portion 132a and the raised portion 122a maintains contact with the corresponding portion of the conductive structure along the second direction X, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132.

[0149] For example, in one embodiment, the restricted portion 132a maintains contact with the corresponding first conductive element 122 along the second direction X, while the raised portion 122a does not maintain contact with the corresponding second conductive element 132 along the second direction X. In this case, the electrical connection between the restricted portion 132a and the first conductive element 122 enables electrical connection between the first conductive element 122 and the second conductive element 132. It should be noted that even if the raised portion 122a does not maintain contact with the second conductive element 132, the spacing between the raised portion 122a and the second conductive element 132 along the second direction X is less than the thickness of the restricted portion 132a along the second direction X, and the raised portion 122a still serves to limit the restricted portion 132a.

[0150] In another embodiment, the protrusion 122a maintains contact with the corresponding second conductive element 132 along the second direction X, while the restricted portion 132a does not maintain contact with the corresponding first conductive element 122 along the second direction X. In this case, the electrical connection between the protrusion 122a and the second conductive element 132 can achieve electrical connection between the first conductive element 122 and the second conductive element 132. It should be noted that even if the restricted portion 132a does not maintain contact with the first conductive element 122, the spacing between the restricted portion 132a and the first conductive element 122 along the second direction X is less than the thickness of the protrusion 122a along the second direction X, and the protrusion 122a still serves to limit the restricted portion 132a.

[0151] In another embodiment, the raised portion 122a is maintained in contact with the second conductive component 132 corresponding to the second direction X, and the limited portion 132a is maintained in contact with the first conductive component 122 corresponding to the second direction X. At this time, the raised portion 122a is electrically connected to the second conductive component 132, and the limited portion 132a is electrically connected to the first conductive component 122, thereby achieving electrical connection between one conductive component 122 and the second conductive component 132.

[0152] In this embodiment, a protrusion 122a is provided on the first conductive member 122, and a limited portion 132a is provided on the second conductive member 132. This allows the first conductive member 122 and the second conductive member 132 to contact and form an electrical connection. At the same time, it can also limit the first connector 12 and the second connector 13, thereby achieving a snap-fit ​​fit between the first connector 12 and the second connector 13.

[0153] In some embodiments, as Figure 9 The figure shows a schematic diagram of the second connector assembly 13 in another specific embodiment, wherein the second connector assembly includes an insulating member 133 and a second conductive member 132, wherein the limited portion 132a is arranged on the insulating member 133, and the second conductive member 132 is arranged on at least one side of the limited portion 132a along the first direction Y.

[0154] like Figure 10The figure shows the state of the first connector 12 and the second connector 13 when the protrusion 122a is set on the first conductive member 122 and the limited portion 132a is set on the insulating member 133. Figure 2 、 Figure 9 and Figure 10 In this embodiment, the first conductive member 122 can be a conductive spring, and the insulating member 133 can be a plastic member. The raised portion 122a is formed by bending a portion of the first conductive member 122, and the restricted portion 132a is formed by protruding a portion of the insulating member 133. When the first connector assembly 12 and the second connector assembly 13 are mated, the raised portion 122a abuts against the corresponding portion of the second conductive member 132 along the second direction X, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132.

[0155] In this embodiment, a protruding portion 122a is provided on the first conductive member 122, a limited portion 132a is provided on the insulating member 133, and a second conductive member 132 is provided on both sides of the limited portion 132a along the first direction Y, so that the protruding portion 122a can abut against the second conductive member 132, thereby realizing contact and electrical connection between the first conductive member 122 and the second conductive member 132, and can also limit the first connector assembly 12 and the second connector assembly 13, thereby realizing the snap-fitting of the first connector assembly 12 and the second connector assembly 13.

[0156] In some embodiments, as Figure 11 The figure shows a schematic diagram of the first connector assembly 12 in another specific embodiment. The first connector assembly 12 includes a first connector 121 and a first conductive member 122. The protrusion 122a is provided on the first connector 121. Along the first direction Y, the first conductive member 122 (the bold line portion in the figure) is provided between the two protrusions 122a.

[0157] like Figure 12 The figure shows the first connector assembly 12 and the second connector assembly 13 in a matching state when the protrusion 122a is provided on the first connector 121 and the limited portion 132a is provided on the second conductive member 132. Figure 3 、 Figure 11 and Figure 12 In this embodiment, the second conductive member 132 can be a conductive spring. The protrusion 122a is formed by a portion of the first conductive member 122 protruding outward, and the restricted portion 132a is formed by bending a portion of the second conductive member 132. When the first connector assembly 12 and the second connector assembly 13 are mated, the restricted portion 132a maintains contact with the portion of the first conductive member 122 corresponding to the portion along the second direction X, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132.

[0158] In this embodiment, a protrusion 122a is provided on the first connector 121, and a first conductive member 122 is provided between the protrusions 122a, and a limited portion 132 is provided on the second conductive member 132, so that the limited portion 132a abuts against the first conductive member 122, thereby achieving contact and electrical connection between the first conductive member 122 and the second conductive member 132, and also limiting the first connector assembly 12 and the second connector assembly 13, thereby achieving a snap-fit ​​fit between the first connector assembly 12 and the second connector assembly 13.

[0159] In some embodiments, as Figure 13 FIG. 1 shows a schematic diagram of another embodiment of the first connector assembly 12. The first connector assembly 12 includes a first connector 121 and a first conductive member 122. The first conductive member 122 includes a first segment 122b and a second segment 122c distributed along a first direction Y. The first segment 122b and the second segment 122c are spaced apart and can be electrically connected via a wiring harness. Raised portions 122a are provided on the first segment 122b and the second segment 122c, respectively.

[0160] like Figure 14 The diagram shows the protrusion 122a being provided on the first section 122b and the second section 122c, the limited portion 132a being provided on the insulating member 133, and the first connector assembly 12 and the second connector assembly 13 being in cooperation. Figure 9 、 Figure 13 and Figure 14 In this embodiment, the first section 122b and the second section 122c can be formed of conductive springs, and the insulating member 133 can be a plastic member. The raised portion 122a is formed by bending portions of the first section 122b and the second section 122c, and the restricted portion 132a is formed by a portion of the insulating member 133. When the first connector assembly 12 and the second connector assembly 13 are mated, the raised portion 122a abuts against the corresponding portion of the second conductive member 132 along the second direction X, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132.

[0161] In this embodiment, a protrusion 122a is provided on the first section 122b and the second section 122c, a limited portion 132a is provided on the insulating member 133, and a second conductive member 132 is provided on both sides of the limited portion 132a along the first direction Y, so that the protrusion 122a can abut against the second conductive member 132, thereby realizing contact and electrical connection between the first conductive member 122 and the second conductive member 132, and can also limit the first connector assembly 12 and the second connector assembly 13, thereby realizing the snap-fitting of the first connector assembly 12 and the second connector assembly 13.

[0162] Alternatively, in this embodiment, a second connector assembly 13 in which the limiting portion 132a is provided on the second conductive member 132 may also be adopted. The specific contents are the same as above and will not be described in detail in this embodiment.

[0163] like Figure 15 FIG. 1 shows a schematic diagram of another embodiment of a connector device 1, comprising a support member 11, a first connector assembly 12, a second connector assembly 13, and a stop assembly 14. Stop assembly 14 is located within a sliding channel 111 and is capable of sliding relative to support member 11 along sliding channel 111. Stop assembly 14 is connected to first connector assembly 12. Along a second direction X, both ends of stop assembly 14 can abut against support member 11 to maintain first connector assembly 12 in a first position within sliding channel 111. Alternatively, stop assembly 14 can maintain first connector assembly 12 and second connector assembly 13 in a mated state in a second position within sliding channel 111.

[0164] like Figure 16 The figure shows a schematic diagram of the first connector component 12 and the limiting component 14 located in the support member 11. The support member 11 has a sliding channel 111 and a first opening 112a. The inner side wall of the sliding channel 111 is provided with a limiting protrusion 111b. The limiting component 14 can abut against the limiting protrusion 111b along the first direction Y to fix the first connector component 12 at the first position in the sliding channel 111.

[0165] It should be noted that, along the first direction Y, the area between the limiting protrusion 111b and the first opening 112a is defined as the limiting area A. The first position in which the first connector assembly 12 is secured within the sliding channel 111 refers to when the limiting assembly 14 abuts the limiting protrusion 111b (the limiting assembly 14 is located within the limiting area A), thereby facilitating the mating of the second connector assembly 13 with the first connector assembly 12. The second position in which the first and second connector assemblies 12, 13 are secured within the sliding channel 111 refers to when the limiting assembly 14 abuts the inner wall of the sliding channel 111, outside of the limiting area A.

[0166] In other embodiments (not shown in the figures), when the limiting protrusion 111b limits the first connector component 12 to any position in the limiting area A through the limiting component 14, the first connector component 12 can be completely located in the sliding channel 111, and at this time the first connector component 12 is arranged close to the first opening 112a, which is convenient for cooperation with the second connector component 13 while reducing the risk of part of the first connector component 12 being exposed to the outside and damaged.

[0167] Figure 16In the embodiment shown, when the limiting protrusion 111b limits the first connector component 12 to any position in the limiting area A through the limiting component 14, part of the structure of the first connector component 12 is located in the sliding channel 111, and another part of the structure of the first connector component 12 can be exposed to the outside of the sliding channel 111 through the first opening 112a to facilitate cooperation with the second connector component 13.

[0168] After the first connector assembly and the second connector assembly are matched, the structure of the two can be located at Figure 17 The location shown can also be located Figure 18 Position shown.

[0169] Specifically, after the first connector assembly 12 and the second connector assembly 13 are matched, when the limiting assembly 14 is located in the limiting area A and abuts against the limiting protrusion 111b, the structure after the first connector assembly 12 and the second connector assembly 13 are matched is located on the outside of the support member 111, as shown in FIG. Figure 17 As pressure is continuously applied to the structure after the first connector assembly 12 and the second connector assembly 13 are mated, the limiting assembly 14 can move below the limiting protrusion 111b, and at least a portion of the structure after the first connector assembly 12 and the second connector assembly 13 are mated extends into the sliding channel 111. The sliding channel 111 protects the structure after the first connector assembly 12 and the second connector assembly 13.

[0170] like Figure 19 The figure shows a schematic diagram of the support member 11. Along a first direction Y, the support member 11 has a top 112 and a bottom 113. The top 112 is provided with a first opening 112a and a first blocking portion 112b. The bottom 113 is provided with a second opening 113a and a second blocking portion 113b. The second opening 113a is arranged opposite the first opening 112a, and the second blocking portion 113b is arranged opposite the first blocking portion 112b. The first blocking portion 112 is used to prevent the first connector assembly 12 from escaping the sliding channel 111. At the same time, it can resist the second connector assembly 13 from being pulled out of the sliding channel 111, thereby achieving the disengagement of the first connector assembly 12 and the second connector assembly 13. The second blocking portion 113 is used to prevent the first connector assembly 12 from escaping the sliding channel 111. The structure and effect of the first blocking portion 112a and the second blocking portion 113a are described in detail below.

[0171] Please continue to refer to Figure 19 The support member 11 has a sliding channel 111 therein, and the inner wall of the sliding channel 111 is provided with the above-mentioned limiting protrusion 111b, which is arranged close to the first opening 112a.

[0172] The cross-sectional shape of the limiting protrusion 111b can be circular, trapezoidal, arc-shaped, triangular, etc., which is not specifically limited in this embodiment. In the following, this embodiment is described by taking the cross-sectional shape of the limiting protrusion 111b as a triangle as an example.

[0173] Please continue to refer to Figure 19 Along the first direction Y, the limiting protrusion 111b has a first limiting surface 111b1 and a second limiting surface 111b2. The first limiting surface 111b1 is located on one side of the first opening 112a and is inclined in a direction away from the first opening 112a. The second limiting surface 111b2 is located on a side away from the first opening 112a and is inclined in a direction close to the first opening 112a, so that the limiting component 14 can move from above the limiting protrusion 111b to below the limiting protrusion 111b, and can also move from below the limiting protrusion 111b to above the limiting protrusion 111b, so that the first connector component 12 and the second connector component 13 can move within the entire sliding channel 111.

[0174] The inclination angle α of the first limiting surface 111b1 and the inclination angle β of the second limiting surface 111b2 satisfy the following: α<β. Figure 17 From the perspective shown, this embodiment sets α<β so that the resistance encountered by the limit component 14 when it moves from below the limit protrusion 111b to above the limit protrusion 111b is smaller than the resistance encountered by the limit component 14 when it moves from above the limit protrusion 111b to below the limit protrusion 111b, thereby ensuring that the first connector component 12 and the second connector component 13 can be mated above the limit protrusion 111b, and that the first connector component 12 and the second connector component 13 in the mated state can cross the limit protrusion 111b and move to above the limit protrusion 111b without causing the first connector component 12 and the second connector component 13 to separate in the process of crossing the limit protrusion 111b.

[0175] Based on the structure of the connector 1 in the above embodiments, the force values ​​that match each other during the removal, insertion, and stroke adjustment of the connector 1 must meet a certain magnitude relationship to achieve the normal insertion and removal function of the connector 1.

[0176] like Figure 17The diagram shows the contact between the limiting component 14 and the first limiting surface 111b1. Along the first direction Y, the resistance to the separation of the first connector 12 and the second connector 13 is the first force value F1, that is, when the pulling force applied to the first connector 12 or the second connector 13 is greater than or equal to the first force value F1, the first connector 12 and the second connector 13 can be disconnected. Correspondingly, when the thrust applied to the first connector 12 or the second connector 13 reaches the first force value F1, the first connector 12 and the second connector 13 can be mated. Figure 4 The first force value F1 may be the force required for the limiting portion and the limited portion to be engaged with each other.

[0177] Along the first direction Y, after the first connector assembly 12 and the second connector assembly 13 are mated, when they move to below the limiting protrusion 111b, the resistance they encounter from the limiting protrusion 11b is a second force value F2. F1 and F2 must satisfy: F2>F1.

[0178] Specifically, F2 represents the resistance of the first connector assembly 12 and the second connector assembly 13 when they are mated and overcome the resistance of the first limiting surface 111 b 1 and move downward in the first direction Y out of the limiting area A.

[0179] In this embodiment, by setting F2>F1, the external force applied to the first connector component 12 and the second connector component 13 to achieve the matching between the two will not cause the limiting component 14 to move downward to below the limiting protrusion 111b, so that the first connector component 12 can complete the matching with the second connector component 13 within the limiting area A, thereby facilitating the matching between the first connector component 12 and the second connector component 13.

[0180] like Figure 18 The diagram shows the structure of the first connector assembly 12 and the second connector assembly 13 mating in another position within the sliding channel 111. After the first connector assembly 12 and the second connector assembly 13 are mated, the second connector assembly can be pushed relative to the first connector assembly to abut against the limit assembly 14. The second connector assembly can then push the limit assembly 14 along the first limit surface 111b1 to below the limit protrusion 111b, and move out of the limit area A. Figure 17 During this process, the first connector assembly 12 and the second connector assembly 13 remain matched and electrically connected.

[0181] As described above, along the first direction Y, the resistance to the separation of the first connector assembly 12 and the second connector assembly 13 is a first force F1. As the limiting assembly 14 slides along the sliding channel 111, the resistance exerted by the inner wall of the sliding channel 111 on the limiting assembly 14 is a third force F3. F1 and F3 must satisfy the following relationship: F1 > F3.

[0182] In this embodiment, by setting F1>F3, when the first connector component 12 and the second connector component 13 are in a mating state, when the second connector component 13 is pressed, the second connector component 13 can drive the first connector component 12 and the limit component 14 to move synchronously in the sliding channel 111, so as to adjust the position of the headrest and prevent the first connector component 12 from being separated from the second connector component 13, thereby improving the reliability of the electrical connection between the first conductive member and the second conductive member when adjusting the position of the headrest.

[0183] like Figure 20 The diagram shows the contact between the stopper assembly 14 and the second stopper surface 111b2. As described above, the resistance to the separation of the first and second connector assemblies 12 and 13 is a first force F1. Following mating along the first direction Y, when the first and second connector assemblies 12 and 13 move above the stopper protrusion 111b, the resistance experienced by the stopper protrusion 111b is a fourth force F4. F1 and F4 must satisfy the following: F1 > F4.

[0184] Specifically, F4 represents the resistance of the first connector assembly 12 and the second connector assembly 13 when they are mated and overcome the resistance of the second limiting surface 111b2 to move upward to the limiting area A. In this embodiment, by setting F1>F4, when a user applies an external force of the fourth force value F4 to cause the first connector assembly 12 and the second connector assembly 13 to move upward over the limiting protrusion 111b in the mated state, the fourth force value F4 will not cause the first connector assembly 12 and the second connector assembly 13 to be disconnected.

[0185] like Figure 21 The figure shows a schematic diagram of the connector assembly installed on a seat. The seat includes a backrest 4, to which a support member 11 is fixed. When the first connector assembly 12 and the second connector assembly 13 mate along a first direction Y and move below the stop protrusion 111b, they experience a second force F2 of resistance from the stop protrusion 111b. Along the first direction Y, the support member 11 experiences a fifth force F5 of resistance to separation from the backrest 4. Specifically, when the pull-out force applied to the support member 11 reaches or exceeds the fifth force F5, the support member 11 separates from the backrest 4.

[0186] In this embodiment, by setting F5>F2, when the user applies external force to the docking device 1 to cause the limit assembly 14 to move upward over the limit protrusion 111b, the external force is less than the fifth force value F5 at which the support member 11 is separated from the backrest 4, thereby preventing the docking device 1 from being separated from the backrest 4 when being pulled out.

[0187] The force values ​​in the above embodiment must satisfy F5>F2>F1>F4, and F1>F3, so that the connector 1 will not separate from the backrest during the plugging and unplugging process, thereby improving the reliability of the first connector assembly 12 and the second connector assembly 13 during the mating and unmating process.

[0188] Please combine Figure 19 and Figure 21 Along the first direction Y, the support member 11 has a top 112 and a bottom 113. The top 112 is provided with a first opening 112a and a first blocking portion 112b, and the bottom 113 is provided with a second opening 113a and a second blocking portion 113b. The second opening 113a is arranged opposite to the first opening 112a, and the second blocking portion 113b is arranged opposite to the first blocking portion 112b. When it is necessary to release the first connector assembly 12 from the second connector assembly 13 (for example, to remove the headrest), the second connector assembly 13 is pulled upward so that the limiting assembly 14 can abut against the first blocking portion 112b. The first blocking portion 112b restricts the limiting assembly 14 and the first connector assembly 12 from continuing to move upward. At this time, the second connector assembly 13 is pulled out under the obstruction of the first blocking portion 112b, so that the first connector assembly 12 and the second connector assembly 13 are released from the engagement, while at the same time restricting the first connector assembly 12 from escaping from the sliding channel 111.

[0189] like Figure 22 The diagram shows an unexpected disengagement of the first connector assembly 12 during mating with the second connector assembly 13. The bottom 113 of the support member 11 is provided with a second blocking portion 113b. If the second connector assembly 13 is inserted quickly, the impact can cause the first connector assembly 12 to slip out of the retaining area A before it can mate with the second connector assembly 13. In this situation, the second blocking portion 113b abuts against a portion of the retaining assembly 14, blocking the retaining assembly 14 and the first connector assembly 12, preventing them from falling onto the backrest.

[0190] like Figure 23 Shown in Figure 22 The state shown is a schematic diagram of the first connector assembly 12 and the second connector assembly 13 mating. At this time, under the obstruction of the second blocking portion 113b, the second connector assembly 13 can be re-engaged with the first connector assembly 12. By providing the first blocking portion 112b and the second blocking portion 113b, this embodiment can realize the disengagement of the first connector assembly 12 and the second connector assembly 13 while also providing a bidirectional anti-detachment function, thereby ensuring the operational stability of the connector device 1.

[0191] like Figure 24 The figure shows a schematic diagram of a specific embodiment of the position limiting assembly 14. The position limiting assembly 14 includes a housing 143, an elastic member 142, and at least two position limiting members 141. The elastic member 142 and the two position limiting members 141 are mounted on the housing 143. Along the second direction X, the two ends of the elastic member 142 are connected to the two position limiting members 141, and at least a portion of each position limiting member 141 can extend out of the housing 143. The elastic member 142 is used to provide thrust to the two position limiting members 141 connected to it at its ends, so that the two position limiting members 141 can maintain contact with the inner wall of the sliding channel 111.

[0192] like Figure 25 The figure shows a schematic diagram of the cooperation between the limit assembly 14 and the support member 11. At this time, the two limit members 141 abut against the inner wall of the sliding channel 111 and compress the elastic member 142, so that the elastic member 142 is in a compressed state and provides thrust to the two limit members 141 to maintain the limit members 141 abutting against the inner wall of the sliding channel 111, thereby realizing that the first connector assembly 12 stays at any position in the sliding channel 111.

[0193] The surface of the limiting member 141 in contact with the inner wall of the sliding channel 111 can be set as an arc surface 141 a to improve the stability of the limiting member 141 moving along the inner wall of the sliding channel 111.

[0194] For further information, please refer to Figure 25 A slider 143a is provided on the outer wall of the shell 143, and a slide groove 111a is provided on the inner wall of the sliding channel 111. When the limiting component 14 moves along the sliding channel 111, the slider 143a slides and cooperates with the slide groove 111a to limit the moving trajectory of the limiting component 14, thereby ensuring the stability of the first connector component 12 / the first connector component 12 and the second connector component 13 moving in the sliding channel 111.

[0195] Alternatively, the outer wall of the housing 143 may be provided with a sliding groove 111 a , the inner wall of the sliding channel 111 may be provided with a sliding groove 111 a , and the slider 143 a may be slidably engaged with the sliding groove 111 a .

[0196] In each of the above embodiments, the support member 11 may include a first support portion (not shown) and a second support portion (not shown), the first support portion and the second support portion being connected to form a first opening 112a, a sliding channel 111, and a second opening 113a. The assembly process of the support member 11, the first connector assembly 12, and the limiting assembly 14 is as follows: first, the limiting assembly 14 is assembled with the first connector assembly 12, then the first and second support portions are placed over the first connector assembly 12 and the limiting assembly 14, and finally, the first and second support portions are fixed.

[0197] This embodiment also provides a seat comprising a backrest, a headrest, and a connector 1. The headrest is detachably mounted above the backrest and can be adjusted relative to the backrest. A support member 11 is mounted on the backrest, and a second connector assembly 13 is mounted on the headrest. A speaker is housed within the headrest. This embodiment utilizes the connector 1 to achieve a detachable connection between the headrest and the backrest, while ensuring proper power supply when the headrest is reattached to the backrest and when its position is adjusted.

[0198] This embodiment further provides a vehicle comprising a vehicle body and a seat, wherein the seat is mounted on the vehicle body. By providing a detachable headrest, the seat can be folded in half or tilted back, greatly enhancing the experience of creating a variety of interior spaces, home scenes, and camping experiences.

[0199] In addition, the connector provided in this embodiment can be applied to any connector usage scenario that requires both plugging and unplugging and power supply.

[0200] In this specification, the same or similar parts between the various embodiments can be referred to each other. In particular, for the device embodiment and the terminal embodiment, since they are basically similar to the method embodiment, the description is relatively simple.

Any changes or substitutions within the technical scope disclosed in the embodiments of the present application shall be included in the scope of protection of the embodiments of the present application.
